It's raining outside and I'm lying in bed sipping coffee and reading after studying for a couple of hours <333

#first time reading a classic in english! #ive read a lot of books in english but never anything written before like #late 20th century #bc i was too intimidated #but apparently my comprehension of english is at that point #where frankenstein isn't too challenging #so that's nice :) #mine #studyblr #chemblr #studyspo #study motivation #chemistry #stemblr #sciblr

Moments before disaster

You see, when potassium Potato Solution meets water tinted with methyl orange in a supposed titration set-up, the reaction will be so reactive that it will cause an explosion.

Stay in school, everyone. It makes you know not to imitate the above set-up in-person.

A team of geologists and planetary scientists from the California Institute of Technology, the University of California Santa Cruz, New York University, and NASA Goddard Space Flight Center reports evidence that Io's volcanic activity has been ongoing since the beginning of the solar system. In their study, published in the journal Science, the group studied sulfur isotopes in Io's atmosphere to determine how long the moon has been volcanically active. Prior research has shown that the solar system is approximately 4.5 billion years old and that Jupiter's moon, Io, is the most volcanically active body in the solar system. But until now, researchers did not know how long the moon has been active. To find out, the research team used data from ALMA to analyze the gases present in Io's atmosphere.

look, I know I've talked about this essay (?) before but like,

If you ever needed a good demonstration of the quote "Any sufficiently advanced technology is indistinguishable from magic", have I got an exercise for you.

Somebody made a small article explaining the basics of atomic theory but it's written in Anglish. Anglish is basically a made-up version of English where they remove any elements (words, prefixes, etc) that were originally borrowed from romance languages like french and latin, as well as greek and other foreign loanwords, keeping only those of germanic origin.

What happens is an english which is for the most part intelligible, but since a lot everyday english, and especially the scientific vocabulary, has has heavy latin and greek influence, they have to make up new words from the existing germanic-english vocabulary. For me it kind of reads super viking-ey.

Anyway when you read this article on atomic theory, in Anglish called Uncleftish Beholding, you get this text which kind of reads like a fantasy novel. Like in my mind it feels like it recontextualizes advanced scientific concepts to explain it to a viking audience from ancient times.

Even though you're familiar with the scientific ideas, because it bypasses the normal language we use for these concepts, you get a chance to examine these ideas as if you were a visitor from another civilization - and guess what, it does feel like it's about magic. It has a mythical quality to it, like it feels like a book about magic written during viking times. For me this has the same vibe as reading deep magic lore from a Robert Jordan book.

The Chemical Structure of Redstone

So I was curious about what the chemical structure of Redstone looks like, and Minecraft Education Edition, albeit unintentionally, gives us a canon look into what Redstone is made of:

In Minecraft Education Edition, putting a Redstone Block into a Material Reducer shows that it's composed of 31 Carbon, 31 Uranium, and 38 Unobtanium, which we can assume to be measured in grams

Dividing the Redstone Block into Redstone Dust, each Redstone Dust is then composed of approximately 3.4 Carbon, 3.4 Uranium, and 4.2 Unobtanium

Again assuming that's measured in grams, that's 0.17 cm³ of Uranium, 1.496 cm³ of Carbon, and ???³ of Unobtanium per Redstone Dust

So what does this tell us about the chemical structure of Redstone? Basing this on Redstone Dust's composition, we can estimate that each Redstone molecule is composed of 3 Carbon atoms, 3 Uranium atoms, 4 Unobtanium atoms, a little under half of the time it binds to an extra Uranium and/or Carbon, and 20% of the time it binds to an extra Unobtanium

This also has some horrifying implications for how Redstone works:

Redstone would be extremely volatile as the radioactive decay from Unobtanium and Uranium would occasionally release Helium ions through alpha radiation, sometimes breaking apart Carbon into two Beryllium atoms (as it absorbs the extra proton and neutron from the Uranium) or merging into Oxygen

So Redstone should, in theory, be extremely flammable and potentially explosive, which implies that cave static, or the player mining Redstone with an Iron Pickaxe, could lead to a spark that causes an explosive cave-in

As Unobtanium is just a placeholder for unobtainable elements (hence the name), I'm going to estimate Unobtanium in this case as Unbinilium, the placeholder name for element 120

Why?

I'm estimating the Unobtanium as Redstone as being larger than the largest man-made element, Oganesson, which holds an impressive 118 protons

Each valence electron shell, from innermost to outermost, can bind with 2, 8, 18, 32, 32, 18, and 8 shells respectively, so I'd like Unobtanium to be an element we haven't discovered yet, and consequently I'd like to jump up to the next shell

While I could estimate with element 119's placeholder, Ununennium, it would have one electron in the next shell, so Unbinilium allows for easier chemical binding

So what does this molecule look like then? Well, horrifyingly...

It looks like this. As Redstone forms in crystal lattices, and only two Carbon atoms are free to bind, I can absolutely see why it's so brittle that it breaks into powder.

This makes the structure of Redstone:

C3U3Uno4 (55% of molecules) C4U3Uno4 (13% of molecules) C3U4Uno4 (13% of molecules) C4U4Uno4 (7% of molecules) C3U3Uno5 (5% of molecules) C4U3Uno5 (3% of molecules) C3U4Uno5 (3% of molecules) C4U4Uno5 (1% of molecules)

An extremely radioactive, flammable, and explosive compound.

A spectrum of neurodegenerative diseases, including frontotemporal dementia (FTD), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD) are due to the accumulation of abnormal, misfolded tau proteins in the brain. A team of researchers has found potential ways to interrupt this process by targeting “sticky” sites along the long form of mutated tau, preventing the misfolding and spreading of the neurofibrillary tangles.

OKAY THIS ARTICLE IS SO COOL

I'm going to try to explain this in a comprehensible way, because honestly it's wild to wrap your head around even for me, who has a degree in chemistry. But bear with me.

Okay, so. Solids, right? They are rigid enough to hold their shape, but aside from that they are quite variable. Some solids are hard, others are soft, some are brittle or rubbery or malleable. So what determines these qualities? And what creates the rigid structure that makes a solid a solid? Most people would tell you that it depends on the atoms that make up the solid, and the bonds between those atoms. Rubber is flexible because of the polymers it's made of, steel is strong because of the metallic bonds between its atoms. And this applies to all solids. Or so everybody thought.

A paper published in the journal Nature has discovered that biological materials such as wood, fungi, cotton, hair, and anything else that can respond to the humidity in the environment may be composed of a new class of matter dubbed "hydration solids". That's because the rigidity and solidness of the materials doesn't actually come from the atoms and bonds, but from the water molecules hanging out in between.

So basically, try to imagine a hydration solid as a bunch of balloons taped together to form a giant cube, with the actual balloon part representing the atoms and bonds of the material, and the air filling the balloons as the water in the pores of the solid. What makes this "solid" cube shaped? It's not because of the rubber at all, but the air inside. If you took out all the air from inside the balloons, the structure wouldn't be able to hold its shape.

Ozger Sahin, one of the paper's authors, said

"When we take a walk in the woods, we think of the trees and plants around us as typical solids. This research shows that we should really think of those trees and plants as towers of water holding sugars and proteins in place. It's really water's world."

And the great thing about this discovery (and one of the reasons to support its validity) is that thinking about hydration solids this way makes the math so so so much easier. Before this, if you wanted to calculate how water interacts with organic matter, you would need advanced computer simulations. Now, there are simple equations that you can do in your head. Being able to calculate a material's properties using basic physics principles is a really big deal, because so far we have only been able to do that with gasses (PV=nRT anyone?). Expanding that to a group that encompasses 50-90% of the biological world around us is huge.
